Alright guys,
For some reason, I keep getting viruses out of nowhere. I reformat my computer, and then several days later, my anti-virus stops working, my IE is disabled, MSN screws up, my computer slows down, and other stuff.
Now, coincidentally, whenever this happens, it always happens after my brother uses my computer. He has reasons for attempting to sabotage my computer, but I won't get into that.
What I used to do was create my account as computer administrator. However, somehow, he can create a new account nonetheless!
One question - how in the world can he do this? Is there any way for me to prevent him from doing this?
Also, is there some program out there that can log what he does while using my computer (installing programs, transfers files, e.t.c.) that is free, and one that he can't find out about?
